WIP: test: local mTLS connection

[rkdefra]

• create local testing SSL assets using the convenience script:

   test/acceptance/setup-mtls.sh

  Using common name: localhost
  This can be changed by passing a command line argument to the script:
  test/acceptance/setup-mtls.sh my-common-name

  Setting up mutual TLS assets...
  ✔ generate private key: ./mtls/ca.key
  ✔ generate certificate signing request: ./mtls/ca.csr
  ✔ sign certificate: ./mtls/ca.crt
  ✔ generate private key: ./mtls/server.key
  ✔ generate certificate signing request: ./mtls/server.csr
  ✔ sign certificate: ./mtls/server.crt
  ✔ generate private key: ./mtls/client.key
  ✔ generate certificate signing request: ./mtls/client.csr
  ✔ sign certificate: ./mtls/client.crt
  MTLS setup complete

• start a simple Node server and make an mTLS request (using the generated assets)

  node test/acceptance/api.ruraldev-mock.js

  handling request...
  valid
  200
  { status: 'ok' }

• adapt the simple server example into a basic KITS mock sufficient for the API's /get-business route

• write an acceptance test to call the /get-business route

• extend the docker compose.yml to add in the KITS mock as a service

• run the acceptance test against the docker composed services to verify correct mTLS compatibility

Closing, as this work has been rebased into main on top of the proper API code in #15
